Specification of Letters Patent.

Iatented July 2, 1907.

Application filed April 8,1907. serial No. 366,945.

To all 'u'hoirt it may concern:

Be it known that I, Ennnm) SONNTAG, a citizenof the United filates, and residing at Chicago, in the county ulilook and State of Illinois, have invented a new and useful Improvement in a Combined Weather- Strip and Window-Supporter, of which.the following is a complete specification. I

This invention relates to improvements in combined weather strips and window supporters and has for its object the production of a device adapted to provide weather tight. jointsforthe sash and which will permit the sash to be raised and lowered with a minimum amount ofl'riction.

It is a further object of the invention to provide device affording an anti-rattling strip, by means of which the sash is resiliently held out of contact with its stops, thus obviating in great measure the noise usually produced by the sash. a I

The invention'consistsof the matters hereinafter described in'the specification and more fully pointed out and defined in the appended claims. 1

In the drawings: Figure l is a perspective view of a device embodying my invention. Fig. 2 is a fragmentary section of a window provided with devices embodying my invention.

As shown in said drawings: Referring first to Fig. 2,

. 11indicate the window frame and 11 and l indicate the stops between which the sash 2' and 3 slide as is usual in such devices. Rigidly engaged in any preclosely against the adjacent stops and are .of a width to extend outwardly from the frame beyond the same and I each terminates in a head 4- which bears on its inner face against the sash. Extending inwardly from said Each of said weather.

bead, and integralthorewith, is a leaf spring 4" extending the full length of the flange and which lies between the sash and said flanges, and divergesfrom the! 'in a bead 4"-which bears against the edge of the sash,

as shown more clearly in Fig. 2; and thereby affording a spring on each side of the sash having two points of contact therewith.

The operation is as follows: Inasmuch as the strip is stationary the sash must slide therein and owing to the fact that the leaf springs 4*press firmly against the sash on both sides thereof they forni a supporter for the sash in. any of its positions. Furthermore the friction usually caused by the movement of the sash is greatly reduced since the beads l and 4 form comparatively slight contact surfaces. Obviously with a device embodying my invention the sash is'prevented from rattling and the joints about the-same are securely closed to drafts and obviously many details of construction may be varied without departing from the principles of my invention.

I claim as my invention: 1. In a device of the class described the combination with a channel of a leaf spring on the inner side or each of its flanges and :1 head on each spring adapted it alTord a bearing surface.

2. In a device of the class described the combination with a channel of a head on the. margin of each of its flanges and a leaf spring extending inwardly from each head and having a head on its inner margin.

3. In a weather strip, a channel having a head on the margin of each flange and a leaf spring extending from each head into the channel, said springs diverging at their inner edges towards the adjacent flange and each having a head on its inner margin.

4. A weather strip comprising a channel having a leaf turned inwardly from each flange and inclined from the edge of the flange towards the base thereof, and longitudinal beads on said leaves affording bearing surfaces adapted to engage the sash.

' In testimony whereof I have hereunto subscribed my name in the presence of two witnesses.
